+ * We want to be able to compile mount on old kernels in such a way
+ * that the binary will work well on more recent kernels.
+ * Thus, if necessary we teach nfsmount.c the structure of new fields
+ * that will come later.
+ *
+ * Moreover, the new kernel includes conflict with glibc includes
+ * so it is easiest to ignore the kernel altogether (at compile time).
